Description

technical field [0001] The invention relates to the technical field of luminescent materials, in particular to a Tb coordination polymer green luminescent material containing conjugated pyridine carboxylic acid derivatives and a synthesis method thereof. Background technique [0002] Iron is one of the ubiquitous elements in our living environment, Fe 3+ Ions widely exist in the environment and biological systems, not only indispensable in organisms, but also play an important role in transporting oxygen and synthesizing DNA and RNA. Moreover, Fe 3+ The lack of ions can disrupt the homeostasis and metabolism of cells, which can cause various serious diseases, such as hepatitis, hereditary hemochromatosis, Parkinson's disease. Too much excess iron present is also toxic and can cause vomiting, diarrhea and intestinal damage. When a person consumes excess iron or is exposed to Fe for a long time 3+ , or repeated blood transfusions, or chronic alcoholism, iron can accumulate...
